GNSS Positioning

Status and Features
Nowadays, GNSS receivers have scores – and often hundreds – of channels, enabling them to track GPS, Glonass, Galileo and Compass signals simultaneously. The whole workflow from satellite tracking to calculating the coordinates of the position in a preferred reference system can be conducted automatically in real time. The price of GNSS receivers has dropped steadily since the first GPS receivers came onto the commercial market in 1982. In conjunction with the latest product survey results for GNSS receivers (available at www.geo‑, the author puts today’s GNSS status and features in perspective.

Hemisphere GNSS Releases New GNSS RTK Engine

Hemisphere GNSS has announced the launch of Athena, its next-generation GNSS engine. According to the company, the new core engine has been designed to maximise the ability to excel at the rigorous GNSS requirements of multiple market segment customers in machine control, survey and GIS. Athena is developed for application in virtually every environment where high-accuracy GNSS receivers can be used. Hemisphere’s customers have tested and proven Athena’s performance in long baseline, in open-sky environments, under heavy canopy, and in geographic locations experiencing significant scintillation. The company claims the brand-new GNSS RTK engine has one of the most reliably consistent... (read more)

Collaboration in GNSS Services

Global Providers Forum Launched
Positioning and navigation by satellites has now become part of everyday life for many citizens all over the globe, and a plethora of (commercial) services rely on the continuous well functioning of these systems. Many more promising applications are in the air and will shape the future landscape.<P> To ensure reliable services the adagio among system providers should be co-ordination and collaboration rather than ignoring one another’s existence. Six nations and federations are now involved in the operational provision or development of Global Navigation Satellite services. In our October Pinpoint the development was discussed of China’s Compass/Beidou Navigation Satellite System... (read more)

X900+ GNSS Receiver

CHC (China) has presented the X900+ GNSS receiver (pronounced “X900 Plus”) which includes GNSS tracking technology for surveyors. The device combines advanced 120-channel GNSS technology (GPS, GLONASS, Galileo and Compass) and RTK reliability and accuracy for either traditional base and rover configuration and RTK networks thanks to its flexible GPRS and UHF communication systems. George Zhao, CEO of CHC, says that the X900+ series is the answer to the recurrent market demand of having a cost-effective yet future proof GNSS technology versus the commonly available GPS+GLONASS architecture. “The X900+ GNSS Solution is offering an exceptional performances to price ratio.” The...

Product Survey GNSS Receivers

In contrast to that of 2005, this product survey on GNSS receivers does not reveal any remarkable technological break-throughs. Manufacturers are increasingly producing systems able to receive Navstar, Glonass and even Galileo signals. This year we have replaced the term GPS (Global Positioning System) by GNSS, because GNSS (Global Navigation Satellite System) better describes the significance and use of these receivers. From providing only position (where am I?) the receivers have evolved into real navigation systems (how do I get to get where I want to go?) The receivers listed here represent the high-end segment of a pyramid-shaped market. Like... (read more)

GNSS and Bicycle Racing

Tour de France
By the time this month's GIM International reaches your desk some two hundred bicycle racers split into 22 teams, numerous service cars, motorcycles, trucks, and more than 4,500 men and woman will be preparing to start, or just have started, the 97th Tour de France.‘Le Tour', as the French have it, is the world's most important bicycle race, and one of the biggest annual, freely accessible events in the public calendar. This year the event will comprise 21 stages and cover a total distance of 3,600 kilometres. The stages vary in scenery and topology, from windy roads in the north-west... (read more)
